Our fastest treatment for clearing green pond water contains 3 times more bacteria than our best-selling pond treatment. The millions of beneficial bacteria that are included in this product target green and murky water and eliminate it for good.

Pond Klear Xtra is a natural pond treatment designed to clear green and murky water by using beneficial bacteria. With three times more bacteria than our original Pond Klear, it works effectively by binding particles together and sinking them to the bottom of the pond. Unlike other treatments that only temporarily address the issue, Pond Klear Xtra tackles the root cause, maintaining clear water by breaking down particles and preventing them from floating back up into the water column.

This treatment is suitable for both filtered and unfiltered ponds, though it may take a bit longer to show results in unfiltered ponds as the bacteria have more work to do. Typically, you’ll begin to see improvements within the first couple of weeks, with complete clarity usually achieved within three to four weeks. Pond Klear Xtra provides a long-lasting solution for clearer, healthier pond water.

Reviews

Disappointed

"Honestly, I think this product is useless. It promised it would clear a pond in 6 weeks but my pond is no better than it was 6 weeks ago. For the first time ever our pond had green water due to the excessive sun we had in south Bucks. We dowsed our pond every week for 6 weeks but the water is still green. We double checked we were using the correct amount so we knew it wasn’t us using it incorrectly. We can’t see any fish at all as it’s so green. All in all I am deeply disappointed and feel I’ve wasted £30 on a product that does not deliver its promise. We have had a pond for over 35 years and this is the first time we have had the pond water go green. Your product was supposed to deliver a clear water pond in 6 weeks and it didn’t."

I have used at least

"I have used at least 3 different treatmrnts this year and Envy was the third one. I still remove some string algae manually, but it is a much, much better water condition now! I think unusual situation with rain and temperatures this yearcreally affected our pond and the gardrn!"

— T C. (4/5)

Excellent product, results were amazing

"Excellent product, results were amazing in just 10 days, and two doses one week apart, in a large pond with fish."

— Shirley J. (5/5)

It actually works

"Have tried many products before all claiming to leave the water in ponds clear. I have found that as long as you clean the filters before using Pond Klear Xtra it does exactly as promised."

Great product, easy to apply

"Excellent, cleared the pond after two treatments and a couple of weeks running through the filter and my pond water was clear again."

— Mark (5/5)

Did the job

"My pond had become very green during the recent hot weather. My usual treatments didn’t seem to be working. After reading the positive reviews I decided to try Envii Klear Xtra. It’s taken 7 weekly treatments but the water is now clear (the label does say that it can take 6 - 8 weeks to clear very green or murky water). I also cleaned the pond filter twice a week, as recommended. It was amazing how much sludge was accumulating in just 3-4 days). You need to be patient as positive results do take time, but I’d highly recommend this product."
